8o AMFRICAN FISHERIFS SOCTFTV 



there bear out what I said. I think you have some lime forma- 

 tion and rocks. 



Mr. DuNNiNc;. — Yes, and some sandbanks. So I want the con- 

 vention, as well as Mr. Fairbank, to think that Wisconsin inland 

 lakes will i)r(>(luce fish — that is, the trout. There is no question 

 about it. 



Mr. Fairbank. — I have no doubt there are lakes where the 

 food will be found. As I say, you find a lake where the proper 

 stone formation exists, and you will undoubtedly find food for 

 them ; but I think in the majority of the small lakes it would be 

 utterly useless to put lake trout in them. I have never heard 

 what the success was there at the Madison lakes. I knew some- 

 thing had been done there, but not the result. So if you have 

 succeeded there you ought to go on and put in a very large 

 amount of them every year. 



Mr. Dunning. — As remarked, it requires different fishing to 

 fish for the lake trout than for tiie salmon. 



Mr. Fairbank. — Yes, you have got to fish for them in deep 

 water. 



Mr. Mather.— Mr. President, there is one thing that strikes 

 me that is a little singular about Geneva Lake, and that is this, 

 as I understand it, the food of all these young fishes belonging 

 to the salmon family, including the brook trout, the lake trout, 

 etc., which are all grouped in one family, there are only three 

 classes of food which they feed upon ; one is the small crusta- 

 ceans, another is the insects and flies on the surface, and the 

 third is the larvae of those flies and worms in the water, and they 

 all feed upon that class of food, and if there is food in Geneva 

 lake for the brook trout and for the California salmon, I do 

 not know why the lake trout should not be found there also. 



Mr. Fairbank. — The brook trout and the California salmon 

 were put into this little stream up above, and there is where thev 

 found their food. There is insect life of course that the cisco 

 feeds on. The young of the cisco find their food there. I don't 

 know what it is.
